The Rise of Cyanobacteria in Freshwater Resources

Cyanobacteria (formerly known as blue-green algae) are on the rise in the U.S. and worldwide, becoming a serious threat to freshwater resources and public health. Research results funded by the National Centers for Coastal Ocean Science are uncovering the secrets of why cyanobacteria are so successful. This information will be used to develop new strategies to control this growing problem. What are Cyanobacteria? Cyanobacteria are one of the oldest life forms on the planet, having been around for nearly 3.5 billion years. These single-celled plants abound throughout the world.

But these tiny life forms also have a dark side. Responding to Outbreaks of Cyanobacteria Humans, the study says, are improving the conditions that cyanobacteria readily thrive in.

What is the cryosphere?

These areas of snow or ice, which are subject to temperatures below 0°C for at least part of the year, compose the cryosphere. The term “cryosphere” comes from the Greek word, “krios,” which means cold. Ice and snow on land are one part of the cryosphere. This includes the largest parts of the cryosphere, the continental ice sheets found in Greenland and Antarctica, as well as ice caps, glaciers, and areas of snow and permafrost. When continental ice flows out from land and to the sea surface, we get shelf ice. 2011-2012 Winter Outlook. Winter Outlook for 2011-2012.
